Insights

MicroRNAs (miRNAs) show promise as biomarkers for kidney diseases. Further research is needed to standardize measurement and explore miRNA-based therapies for kidney and cardiovascular conditions.

Area of Science:

  • Molecular Biology
  • Nephrology
  • Genetics

Background:

  • MicroRNAs (miRNAs) are small non-coding RNAs regulating gene expression.
  • miRNAs play a crucial role in kidney physiopathology.
  • Their involvement spans various kidney disease models and patient groups.

Purpose of the Study:

  • To review the role of miRNAs in kidney diseases.
  • To discuss their potential as biomarkers in nephrology.
  • To explore innovative miRNA-based therapeutic strategies.

Main Methods:

  • Literature review of miRNA involvement in kidney disease.
  • Analysis of miRNA roles in cellular and animal models.
  • Examination of miRNA implications in patient cohorts (CKD, AKI, hemodialysis, transplant).

Main Results:

  • miRNAs are implicated in diverse kidney disease contexts.
  • Current evidence suggests miRNAs as potential diagnostic and prognostic biomarkers.
  • Challenges include cohort size and method standardization for clinical utility.

Conclusions:

  • miRNAs hold significant potential as biomarkers in nephrology.
  • Standardization of measurement and selection of appropriate biofluids are critical.
  • Targeted modulation of deregulated miRNAs offers innovative therapeutic avenues for kidney and related organ damage.

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

Kidney Structure01:45

Kidney Structure

The kidneys are two large bean-shaped organs located in the upper abdomen. They filter the blood several times a day to remove toxins and rebalance water and electrolytes of the circulatory system via the renal veins. The kidneys receive blood directly from the heart via the renal arteries. These arteries enter the kidney at the hilum, the concave surface of the bean, where they branch and divide into smaller vessels and capillaries.

Pathophysiology of Diabetes

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
